The Application of Suspended Granular Sludge Technology In The Design of High-rate Anaerobic Reactors

Anaerobic process in the wastewater treatment, owing to its inherent priority in application, attracted people much attention in recent years. Followed that, the third generation of novel types of high-rate anaerobic reactors, such as EGSB and IC was also invented. In this paper, the mass transfer status and flow pattern in these anaerobic reactors are described by view of the reactor's macrokinetics; Design methods of such high-rate anaerobic reactors with suspended granular sludge technology were summarized in details. Finally, the future development of this field was prospected.
